Speceaton of Letters Patent.

Patented sept. l24, 1907.

Application filed June 3,1907. Serial No. 376,995.

To all whomr 'it may concern:

Be it known that we, WALTER 1). EVANS and GHARLns W. Gaan, citizens oi' the United States, residing at Meadow Grove, in the county oi Madison and State oi' Nebraska, have invented certain new and usel'ul Improvements in Ealing-Presses; and we do declare the following to be a full, clear, and exact description o1 the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to baling presses, and more particularly to an automatic tier lor the same; and has l'or its object to provide a device ol this kind which can be applied to presses oi different construction7 and is adapted to be operated automatically by the action oi the plunger whenever the bale being formed has reached the desired length or dimension.

1n the accompanying drawings, which illustrate the invention,-Figure 1 is a top plan view of a portion oi a press embodying the invention; Fig. 2 is a side clevation of the needle; Fig. 3 is a similar view from the opposite side; Fig. 4 is a longitudinal sectional view of the same with a portion el the press; Fig. 5 is a transverse sectional view taken near the rear end of the needle and with the looper shown in elevated position; Fig. 6 is a broken side elevation of the looper detached; Fig. 7 is a broken enlarged side elevation oi the tripping mechanism.

Referring more particularly to the drawings, 1 indicates the press, which may be oi any desired construction, having an ordinary baling chamber 2, feed chamber 3, and reciprocatory plunger Lt.

The sides oi the press are provided with openings 5 at a point substantially between the iced chamber and the baling chamber, one above the other, for the passage ol the needles 6 ior the purpose oi tying the binding wire around the bale, two wires being generally used tor such purpose.

The needles are exact duplieatesol each other, and therefore, a description of one will apply to both. 1n their normal or inoperative positions the needles are supported on tracks 7, which extend laterally from one side oi the press at the lower portions of the openings 5. The track is preferably provided with facing recesses 8, which may be formed by means of substantially U- shaped metal bars within which the needles are adapted to be reciprocated.

Each needle consists of two parallel bars 9, which are preferably substantially inverted T-shape in cross scction, spaced apart by cross pieces 10, with the outer portion 11 oi each head oi the T fitting in the recesses 8, The upper edge ot' each bar is formed or provided with a ange 12, which overhangs the inner portion of the head oi' the T and thereby forms a trackway l'or the knetter or mechanism lor joining the ends ot' the wires and twisting them together. The knetter consists oi a base 13, which has its sides provided with depending walls 14, which lit in between the ilangei12 and the inner portion oi the head ot the- T bar.

.lournaled upon the under side oi' the base is a gea-1' wheel 15, which is adapted to engage with a rack 16, which is secured at its ends to two oi the cross pieces 10 at one side oi the center ol the track 7 The upper face of the wheel 15 is beveled and provided with gear teeth 17, which are adapted to engage with a bevel pinion 18 journaled at one side of two upwardly eX- tending walls 19.

The shaft ot the pinion between said walls is provided with a pinion 20, which engages with two other pinions 21, one upon cach side and near the upper edge of the walls 19. The pinions 21 are each slotted xradially, as shown at 22, which slots are adapted to register with slots 23 in the walls 19. Two hooks 24 are pivotally mounted upon one oi the walls 19, each hav ing its upper end curved, as shown at 25, which is adapted to normally extend across one ol the slots 23, whereby the wires may be inserted into the slots by forcing the hooks back out oi the way against the tension of a spring 26, after which, it will be impossible for the wires to be removed, on account oi the hooks 24.

Two standards 27 and 2S are located at a short distance from the rear wall 19, andone of them is provided with a perforation 29, through which the wire is passed through to the slot 22 in one of the pinions 21. Pivotally mounted upon the standards are two knile blades 30, which are adapted to be forced against the sides oi the standards by means of a lever 31, that is pivoted at one end to the rear wall 19, and has its intermediate portion slotted for engaging with the heels or inner ends oi the knife blades 30, when the tree end of the lever is raised. The free end oi the lever has its under surface curved, as shown at 32, whereby it is adapted to engage with a projection 33 upon one of the cross pieces 10, the projection being substantially triangular j and having its iront and rear walls inclined for the purpose of engaging with the lever 31 and swinging it upward, for the purpose of cutting the baling wire, by means of the blades 30. The weight of the lever is such that its free end normally hangs down far enough to keep the blades away from the standards, for the insertion of the wires. i

Journaled transversely ot' the knotter frame or base 13 is a shaft 34, one end of which is provided with a double mutilated gear wheel 35, and the other end is provided with a cam 36, having a [iat face 37, whereby the shalt may be locked against rotation. The intermediate portion of the shaft is provided with a bale-like looper 38. The looper is adapted to lie substantially flat or even with the knetter frame when in its inoperative position, with a standard 39 projecting upwardly from the base 13 between the sides or legs 40 of the looper; and it is adapted to have its free end swung over the walls 19 and adjacent to the standards 27 and 28, the legs being curved, as at 41 for this purpose. The legs are provided with notches or recesses 42, which are adapted to register with the slots 23. and with the open knife blades 30, the notches nearest the shaft 34 being formed between diverging prongs 43. The free end of the looper is preferably provided with a grooved wheel or pulley 44, over which the wire is adapted to pass from the notches 42 upon one leg to those upon the other leg.

The shaft is adapted to be rotated by means of two short racks 45 and 46, one of which is located at one side of the press in position for engaging with the gear teeth 47 of the wheel 35 for the purpose ef swinging the looper from its normal position to form loops in the wire; and the other rack is located upon the side of the needle frame in position for engaging with the teeth 48 for returning the looper to its normal position while the knot is being tied.

The standard 39 is provided with a horn 49, which is recessed at its base, as shown at 50, and a knife blade 5l is pivotally secured to the standard below the said recess in position for having its knife edge forced up past said recess when its free end engages with an inclined projection 52 upon the cross bar 10 at the forward end of the needle, and thereby sever the wire that has been drawn into said recess.

Journaled lengthwise of the knetter frame upon one side in brackets 53 a shaft 54, which has two oppositely extending horn-like projections 55 at one end, and a lateral bend 5G at tbe other for rotating the shaft when said bend is forced into engagement with an inclined plate or blade 57 secured to one side of the press. A hook-like projection 58 projects laterally from the intermediate portion of the shaft 54 substantially in alinement with the recess 50, in the horn 49 and coacts with a bracket 59 secured to the side of the baler on the other side of the knetter for the purpose of assisting in forming the loops in the wires when the looper is swung from its forward or normal position to the rca In the drawings the projection 58 is shown as being secured to the shaft 54 by means of a collar G0, which has a portion of its rear end formed into a cam G1 for engaging with the flat portion 37 of the cam 3G and thereby locking the shaft 34 against rotation.

A spring tongue G2 is secured to one side of the press and has its free end inclined, as shown at 63 and provided with two shoulders 64 and G5. One ofthe shoulders, as G4, is adapted to engage with a loop or projection GG upon the bottom of the base 13 and hold the knetter against return movement when the knot is being tied, and the other shoulder is adapted to be engaged by a projection G7 upon the forward cross bar 10 to force the shoulder 64 down out of engagement with the loop (S6 after the knot has been tied, and thereby permit; of the return of the needleA A guard returning wall 68 is secured at its ends to the inclined blade 57 fer the purpose of engaging with the lateral bend 56 of the shaft 54 for the purpose of returning said shaft to its normal position, thereby locking the looper in its inoperative position, and also throwing one of the wires out of one ofthe pinions 22, by means of one of the horns 55 when the needle is being withdrawn.

Two spools of wire G9 and 70 are mounted upon opposite sides of the press in any desired manner, and the wire 71 from one of them is adapted to be passed through the perforation 29 in the standard 27, and the wire 72 from the other spool is adapted to be passed through a perforation or recess 73 in the outer end of the bracket 59, and the ends of said wires are provided with interlocking loops 74, whereby the two wires are caused to extend across the press in position for being engaged by the 1n ateria-l and carried forward with the end of the bale, as it is being gradually formed by the reciprocation of the plunger'.

The needles are adapted to be reciprocated in any desired manner, one of which is shown in the drawings, and consists of a rock shaft 75, which is journaled vertically upon one side of the press, and is provided with two arms 76, the free ends of which are adapted to be connected with the respective needles by means of links 77. The rock shaft is adapted to be actuated in any desired manner, as by means of an arm 78, which extends across the pitman for the plunger and is adapted -to be engaged by two shoulders 79 and 80, formed thereon, preferably near one edge, as in a flange 8l.

rl`he arm 7 8 is adapted to normally enter the recess between the shoulders 79 and 80, as by gravity or spring pressure, but is normally held out of engagement with the plunger by means of a block 82, which is provided with a shoulder 83. An inclined wall or surface 84 is located near the shoulders 79 and 80 when the plunger is at the rear limit of its stroke, with which the arm '7S is adapted to engage, and thereby be raised out of en- '^`ge1nent with one of the shoulders, as 79, but not out of position for being engaged with the other shoulder 80, which is higher than the shoulder 79.

The block 82 is adapted to be drawn out from under the arm 78 by means of a cord 85, which is adapted to be wound around upon the hub of a toothed wheel 8G. The wheel 8G is journaled in one end of a lever 87, which is pivoted in a bracket 88 upon one side of the press. The other end of said lever is adapted to be engaged by apin or projection 89 upon one of the needles 6, whereby the wheel 86 is moved out of engagement with the bale, which permits a coiled spring 90 to return the block 82 to its normal position. While the arm 78 is resting upon the inclined wall 84, the lever 87 is returned to its normal position with the wheel 86 in engagement with the bale of hay by means of a coiled spring 91.

ln operating a press as above described, the needle is withdrawn to its outer limit, and the knetter placed upon the forward en d of the needle, preferably by causing it to engage with a suitable stop secured to the side of the press. The wire 71 is then passed through the perforation 29 and the slots 22 and 23 and securely fastened to the end of the wire 72, which has been passed through the perforation in the end of the bracket 59. The material is then fed into the press in the ordinary manner, which is carried forward against the two wires by the plunger in the ordinary manner, which will gradually carry the wires down into the baling chamber in front of the bale, thereby drawing the wire equally from the spools upon the opposite sides of the press. As the bale moves forward the wheel 86 gradually winds up the cord 85 and pulls the block 82 from under the arm 78 until the arm finally drops off the shoulder on the block into the recess between the shoulders 79 and 8O on the plunger. As soon as the plunger starts on its rebound, the shoulder 79 engages with the arm 7 8 and carries it to the rear, thereby rocking the shaft and causing the arms76 and links 77 to force the needleacr'oss the press to the rear ot the finished bale. When the needle starts forward the strain of the wire against the side of the bale will hold the knetter stationary while the needle moves forward the length oi the rack 1G, or until it reaches the rear end of the needle head. The

krrotter and needle are then carried lor'ward with the wir'e 71 passing through a perleration in the rear end oi an arm 92, which is secured to the knetter, and from there it passes through the perforation 29 to the twister head or pinion 21 at that end oi the walls 19 and around the grooved wheel 44 with one portion ofthe wire adjacent to the bale lying between the horns 55. As the needle moves iorward it passes under the por'tion el the wire 72, which passes down the opposite side of the bale, and thereby draws said wire inte the recess 50 under the horn-like projection 49, and also in front of the projection 55, which has been turned up by that time by the engagement 4el the lateral bend 56 with the inclined plate or helder 57. By the time the needle has r'cached this point, the shalt 54 has been rotated lar enough to unlock the shalt 34 and also to cause the gear teeth 47 on the wheel 35 to engage with the rack 45, and thereby rotate the shalt 34 and swing the loopcr 38 te the rear, folding the two portions el the wire 71 over the wire 72 and also bending the wire 72 back tewar'd the slotted pinion or twister heads 2l. The rotation et the shalt 54 causes one oi the horns 55 to carry the wire above the slots 22 and 23 at that end oi the walls 19. As the leoper is carried l'rackward by the engagement oi the teeth 47 with the rack 45, the notches 42 lorrned therein will engage with said wires, and torce them down into the slots 2,2 and 23 past the hooks 24 with the portion oi the wire upon each side ei the loeper between the prongs 43 and the notches 42 near the wheel 44 in between the kniie blades 30 and the standards 27 and 28. By the time the parts el the knetter have reached the position as above described, the needle has reached the limit of its lorward movement, and has caused the loop 66 to engage with the shoulder G4 and thereby hold the knetter' against return movement with the needle. As soon as the needle starts on its return movement the lever 31 is lilted by the projection 33, which causes the blades 30 to cut ed the portion of the wire that extends around the grooved wheel 44. By the time this has been done, the gear teeth 48 engage with the r'ack 46 and return the looper' 38 to its normal position. The further return rnevement o the needle, while the knetter' is thus held stationary, causes the projection 52 to pass under the r'ee end ei the knife blade 51 and torce it up against the hor'n 49 and sever the portion of the wire 72, which has been drawn transversely across the needle trom the bracket 59 and has been connected with the portion of the wire 7l, which has been placed across thel rear end el the bale. As soon as this has been done, the projection G7 engages with the shoulder 65 on the spring 62 and forces the shoulder 64 down out of engagement with the loop 66. The further movement te the rear et the needle will carry the knetter mechanism with it, with the wire 71 passing through the perforation in the ar'm 92 and through the perforation 29 and pinion 2l4 By providing the arm 92, there is always a suliicient amount ol; wir'e 7l. drawn from the reel during the slower movements el the press to afford enough slack that when the needle is carried across the baling chamber its rapid movement caused by the rebound o the plunger will prevent the liability et breaking the wire. At the same time that the needles reach the limit ol their forward movement, the pin 89 upon one of them engages with the lever 87 and moves it se as to release the toothed wheel S6 from the bale, and thereby permits the coiled spring 9() to draw the block 82 under the arm 78, so as to hold the arm out of the path oi the shoulder 79, and thereby permit the free reciprocation el the plunger alter the shoulder SO has carried the arm 7S forward to withdraw the needles as above described.

From the loregoing description, it will be evident that the needle and knot-tying mechanism can be easily applied to any ordinary press, and thereby automatically tie each bale as soon as it is formed. In this manner, the operation ot baling can be continuous, and the size oi the bale can be changed or varied at any time by lengthening the cerd 85 er by manually withdrawing the wheel 86 from engagement with the bale and unwinding or winding up a portion of the cord, as the case may be, to withdraw the block from under the arm of the rock shaft, sooner or later, as it is desired to have the length et the bale greater or less.
